Description

Data forwarding method, device and system

The present invention relates to the field of communications technologies, and in particular, to a data forwarding method, apparatus, and system. Background technique

Virtualization software uses software technology to simulate the creation of multiple virtual machines (VMs) on a single physical computer. Each VM can be installed with the operating system, installed application software, and runs various programs as a physical computer. Multiple VMs can run on a single physical computer at the same time. They don't perceive each other, are isolated from each other, and can communicate with each other only through the network, just like two physical computers. The combined performance of multiple VMs does not exceed the physical computer on which they reside.

In virtualization technology, software that simulates multiple VMs on a single physical computer is called Virtual Machine Monitor (VMM). Since virtual technology introduces the middle layer of VMM, the nature of the applications running inside the VM is different, and the performance loss caused by virtualization is also different. An application that performs a large number of CPU operations with less performance loss when running in a VM. Applications that communicate with the outside world with a large number of input/output (I/O) communications (such as network communication or disk read and write) have a large performance penalty when running in a VM. As virtualization technology can bring better overall cost advantages, the wireless communications industry is beginning to adopt virtualization technology on a large scale. However, in wireless communication devices, applications often require a large amount of network communication and a large amount of data is swallowed, so the performance of the application in the VM is greatly reduced.

In the prior art, the standard virtualized I/O communication mechanism is used to exchange data between the internal and external communication ends of the VM, and the data is exchanged with an efficient interface, which simplifies the simulation process of the virtual hardware and reduces the loss of the I/O process. . However, although this solution reduces the loss, the loss is still large. The prior art also refers to Single Root I/O Virtualization (SR-IOV). The hardware straight-through technology will be a physical computer. The hardware on it is handed over to the VM instead of the virtual hardware virtualized by the VMM. In this technology, the driver in the VM can directly drive the physical network card to perform packet transmission and reception operations. The VM bypasses the intermediate process of the VMM directly using physical hardware, minimizing performance loss. However, because VMs need to perceive different physical hardware and install corresponding drivers for different hardware, the VMs need to be changed together during hardware upgrade or change, which has a great impact on the development, maintenance, and deployment of VMs, resulting in reduced work efficiency. Actual operation is also more troublesome. Summary of the invention
